Automatic Failover = Constant Link State
Deploying in-line monitoring devices such as intrusion prevention systems (IPS) or bridge devices like VPN gateways and firewalls used to mean a potential point of failure on the network. When one of these devices malfunctioned or became overwhelmed with traffic, network outages could occur. This posed serious challenges when deployed on mission critical links.

The DURAstreamÂ™ Bypass Switch ensures your networkÂ’s most important data does not fail even when in-line devices do. Deploying a DURAstreamÂ™ Bypass Switch ensures uptime of critical links regardless of in-line device performance by diverting critical network traffic away from malfunctioning in-line devices until such devices are operating normally. This not only alleviates potential issues with traffic congestion affecting link behavior caused by an IPS, it allows maintenance and upgrades of attached in-line tools without network downtime.

The DURAstreamÂ™ 4000 1G Bypass Switch is an easy-to-manage external active bypass providing failover and TAP capabilities for data monitoring of critical Gigabit network segments. Each bypass switch offers up to four independent interface modules with a variety of media options (copper, fiber, and media conversion). Each of the four network modules operates independently to ensure link protection monitoring of one to four links at any time.

Heartbeat Mode
The DURAstreamÂ™ 4000 1G Bypass Switch can monitor the health of in-line appliances by sending and receiving a heartbeat packet. A user programmable heartbeat packet can be injected into the monitoring port link to determine availability of attached monitoring devices or help determine delay due to high traffic volume.

Even if a connected in-line tool is powered on, the bypass switch can automatically switch traffic around it until the device returns to normal operation. At that time, traffic is re-routed back to the monitor port.

Passive Mode
In the event of power loss, the switch closes to create a physical connection, which in turn, creates a passive bypass path to help prevent traffic interruption.

Reliable and Easy to Use
The DURAstreamÂ™ 4000 1G Bypass Switch is simple to deploy, enables plug-and-play connectivity, and is compatible with all major manufacturerÂ’s monitoring systems. Every unit not only comes with dual redundant power supplies to ensure monitoring uptime, the voltage of each power supply is continuously monitored for instances of power decline or outage. In such cases, the unit can initiate a switch to passive bypass mode.
